ENGINEERING and advisory support company Xodus Group has delivered an integrated production modelling simulation suite for Origin Energy for use at the Australia Pacific LNG project.

Carrying out detailed modelling of both the compression facilities and the high pressure pipeline network at APLNG, Xodus staff helped to create an interactive user interface which accurately simulated the gas delivery network to allow Origin to run fully automated operating scenarios.

The team used AspenTech’s HYSYS steady-state linked with Microsoft Excel software to simulate several aspects of the project demonstrating novel and world leading simulation capabilities.

A further scope of work involved the use of HYSYS dynamics to produce a hi-fidelity mimic of Origin’s centrifugal compressor control system to fully verify its design prior to installation.

The value of both contracts was about $300,000, Xodus said.

Xodus’ general manager in Australia Andy Jones said the project required a forensic, in-depth knowledge of the inner workings of the simulation software in order to produce a bespoke solution.

“We used specialist programming techniques to achieve a complex model unlike anything that has been produced before,” he said.

“It allows Origin to run very detailed operating case scenarios to optimise operating conditions, balancing project critical factors such as power usage versus line pack availability.”
